DETACHABLE HEEL.

To all whom it may concern:

Be it known that we, LINK SMITH, Srnrnrx D.. McOslu-zn, and Jaatns R. qnsirsox, citi- Zens of the United States, residing at Enid, in the county of Garfield and State of Oklahoma, have invented certain new and useful Improvements in Detachable Heels, of which the following is a specification.

This invention relates to the shoe heels, more particularly to "heels of rubber or like material, and has for one of its objects to provide a device of this character which may be readily applied to the shoe by any person without previous skill or knowledge, and which may be readily detached for renewal or repair withoutdiscardingthe remainder of-the shoe.

\Vith-these'and other obiects in view, the

invention consists in certain novel features of construction, as hereinafter shown and describettaud then specifically pointed out in the claims; and in'the-drawingsillustrative of the pretcrred embodiment-oftheinvent-1on- Figure 1 is a perspective view of-the heel portion of a shoe with the improvedheel applied, I

Fig. 2 is a sectional elevation,

Fig. 3 is a detached perspective view of the metal anchor plate.

The improved device comprises a' heel formed of rubber or'like material and having a plate embodied therein with spurs projecting from the plate through the upper face of the heel and adapted to enter-the heel portion of the sole of'the shoe and support the heel from horizontal displacement. The plate which is embedded within the body of the heel is formed with a threaded aperture to receive a holding screw which is passedthrmlgh the heel portion of-the sole of the. shoe and the intervening portion of the ruhierheel and into the. threaded aperture of the plate. By this means the heel is firmly connected to the'heel portion of the sole, and can be quickly applied or removed "for renewal or repairs.

lnthe drawings a portion of a shoe is shown including the body 10, the sole 11. and the insole l2. The improved device may he applied without 'material structural change. to diil'erent structures of shoes, and it is not -.lesired to limit the invention to any specific form or size of shoe. The heel portion of the. shoe is represented as a' whole at 13 and is molded into the requiredshape Specification of Letters Patent.

from rubber or like material, preferably the same composition usually employed in the manufacture of rubber heels. The holding I referred to is represented at 14 and is embedded or vulcanized within the body of the material of the heel as illustrated in Fig. "2. Theplate 1.4: is increased in thicknessat the center and the thickened port-ion' provided with a threaded aperture represented at 15 to receive the threaded terminal of a holding bolt or screw 16. The bolt extends through the upper portion of the heel andthrough the heelportion ot-the sole 11 coveredby-the insole 12. The upper end otthe bolt-is laterally enlarged in'flat form as shown at 17.-the enlarged portion 't'orn'iing The head '17 -is;provided with a screw-driver receiving slot. sothat the boltinay be-rotated to draw the-heel 13 firmly into engagement with the sole ofthe shoe and firmly support it from displacement. The sole ll is slightly rcccssed adjacent the aperture for the bolt to receive the lower face of the head 17, while the lower face of the insole 12 is likewise recessed to receive the curved outer face of the head. By this means the bolt head does=not-- produce a protuberance or projection at the-heel of the shoe. The plate- 1 is provided with a plurality of relatively sharptongues -20, preferably formed by euttin; V shapcd clei'ts through the plate and bending the material between the cletts substantially at right. angles tothe face of the The. tongues are designed to project through the intervening portion of the body of the. heel 13 and enter the. sole 11 of the shoe, to hold the heel from horizontal displacement, and coact with the bolt 10 to hold the heel in. place. The plate. 14 is likewise provided with numerous relatively large apertures 21 into which the material of the heel will enter during the vulcanizing process to further anchor the plate within the mate- 'rial of the heel.

single flat relatively thin reinforcing plate of the general'contour of the heel embedded in the body portion near the attaching face thereof and provided with a plurality oi upstruck substantially V-shaped spurs disposed on one side of the plate only and spaced inwardly from the marginal edge thereof with certain of the spurs extending diagonally across the breast corners of the plate, said spurs being arranged in triangular form with the points of the spurs normally projecting through and beyond the attaching face of the heel, the central portion of the plate being thickened and provided with a centrally disposed threaded opening for the reception of a fasteningdevice, there being a plurality of openings formed in said plate between-certain of the spurs and disposed concentric with the central opening and a plurality ofsmaller openings extending entirely around the plate near the marginal edge thereof.

2. The combination with a shoe including an outer sole and'an inner sole, theconfronting faces of which are formed with registering depressions, oi a rubber vheel :having a "single reinforcing plate of the general oon-- tour of the heel' embedded therein near the across the bre st corners of said plate, the

points of the)spurs being disposed on one side of the plate only and normally extending through and beyond the attaching face of the heel and into the outer sole of the shoe, and a securing element having its lower end threaded for engagement with the threaded openingin the plate and its upper end provided with an enlarged head seated in the depressions in the outer and inner soles, respectively.

In testimony whereof we affix our slgnatures.
